Suitable detectors for circulation and living areas.
Domestic alarm systems
Smoke, heat and CO alarm installation in London
Alarm installation, replacement and wiring for homes and rental properties, with device type and location matched to the agreed requirement.
Service overview
The right detector in the right position matters.
Smoke, heat and carbon-monoxide alarms perform different roles. Property layout, fuel-burning appliances, escape routes, local requirements and existing wiring all influence the correct arrangement.
Bastian Electrical can assist with suitable mains-powered, battery-backed and interlinked alarm installations, replacements and fault investigation.
Where a landlord, building-control or fire-risk requirement applies, the relevant specification should be provided or agreed before installation.
Domestic alarm installation does not replace a fire-risk assessment or specialist system design where one is required. Commercial fire alarm work is treated separately.

Helpful answers
Questions about this service
What is the difference between smoke and heat alarms?
Smoke alarms detect smoke particles, while heat alarms respond to temperature. Heat alarms are often used where normal cooking fumes could trigger smoke alarms.
Can alarms be interlinked?
Suitable alarms can be wired or radio-interlinked so activation of one sounds the others.
Do mains alarms have batteries?
Many mains alarms include battery backup. The exact product and replacement requirements depend on the selected system.
Can you replace an old alarm with a different brand?
Compatibility of bases, interlinking and wiring must be checked. A full compatible set may sometimes be the better option.
What alarms does a landlord need?
Requirements depend on location, property type, tenure, licensing and current rules. The relevant landlord or authority specification should be checked.
Do you install commercial fire alarms?
Bastian Electrical offers defined electrical wiring support where a suitable design and responsibilities are provided; specialist design and commissioning may require a fire-alarm company.
